To all whom it may concern:

Be it known that 1, James G. BARRETT, a citizen of the United States, residin at Williamstown, in the county of Berks 're and State of Massachusetts, have invented a new I and useful Rail-Holding Means, of which the without altering or injuring said rail.

A further ob ect is to provide a structure thatwill be very durable and is not liable to derangementor injury from ex osure to the elements and to the jars and vi rations incident to the track held thereby.

An embodiinentof the invention that is at present considered the preferable one is illustrated in the accompanying drawings but an inspection of the claims will clearly show that said invention is not limited solely to the embodiment disclosed; I

In the drawings, Figure 1 is a side elevation of a portion of a track with the holding means applied to the rail thereof. Fig. 2 is a cross-sectional view throu h the same. Fig. 3 is a longitudinal sectiona View taken on the Fig. 4 is a horizontal sectional view taken on the line 4 4 of Fig. 2. Fl 5 is a bottom perspective view of the ho ding-plate and the associated portions of the jaws. Fig. 6 is a perspective view of one of the rail-engaging earn elements.

Similar reference-numerals designate corresponding parts in all the figures of the drawln the structure illustrated two adjacent ties 7 are shown, upon which is located the ordinary railroad-rail 8. Fitted between the ties and beneath the rail is ananchor-block 9,

that may be of any suitable material, said block thus being held securely in the ballast. Embracing the anchor-block are jaws 10, having their upper ends enlarged, as shown at 11, said up er ends terminating in inwardlyextending ills 12, that engage over the baseflange'of-the rail, as clearl shown in Fig. 2. The inwardly-extending ills are provided with sockets 13, these sockets receiving the outer tapered ends of freely-swinging cam .vices.

elements 14. The said cam elements, as disclosed in Fig. 4, have pivoted hearings in the sockets, and their inner opposing ends are provided with curved surfaces 15, that are disposed eccentrically. to the axes of movement of the elements. The curved surfaces are arranged to bear against the opposite faces of the rail-web. i I

The jaws 10 are connectedby spaced de- One of these devices is in the form of a plate 15, located transversely beneath the anchor-block and having longitudinallydisposed slots 17. The lower ends of the jaws have reduced portions 18, which pass through the slots, said jaws terminating at their lower end in transverselydisposed heads 19. The heads 19 are of less width and less length than the slots 17 and arch located transversely of the same when the arts are in their normal relation. This, it is believed, will be apparent by reference to Fig. 5. It will also be clear that when the jaws are turned sidewise the heads can freely pass through the slots, and when placedln position upon opposite sides of the anchor-block, being disposed transversely of said slots, the parts will be securely interlocked. The intermediate portions of the jaws are connected by attic-bolt 20, prefer,- ably angular in'cross-section, this tie-bolt extending beneath the rail and being seated. in a recess 21, formed in the anchor-block.

The said tie-bolt passes through 0 enings made in the enlarged portions 11 of t e jaws,

one end of the bolt having a suitable head 22, the other end having a nut 23 threaded thereon, which constitutes an adjustable clamp for drawing the jaws toward. each other. I

It will be apparent that when the structure is in position on a rail it will be securely anchored in the ballast, as said anchor-block is not only in said ballast, butabuts against the-adjacent ties. The aws 10 are likewise embedded, and, furthermore, because of the tie-bolt 20 engaging in the slot 21 of the anchor-block said jaws cannot slip along the block. The .freely-swingin cam elements will bind strongly against t e rail-web, and in case said web starts to move in either di-' rection the elements will swing upon their pivot-axes, causing the camor eccentric surfaces to move toward each other, and thus more securely bind upon the rail. By this structure rails can be fastened securely against creeping or longitudinal movement in either direction. The apparatus is simple and is made up of parts not liable to breakage or derangement.

From the foregoing it is thought that the construction, operation, and many advantagesof the herein-described .invention will 4e apparent to those skilled in the art without further description, and it will be undereluding an upstanding device having a socket in its inner end, of a freely-swinging cam element having its outer end pivotally mounted in the socket-and having a rail-engaging surface that is disposed eccentrically to the axis of movement of said element.

' .2. In a device of the character described, the combination with anchoring means 'including a clamping-jaw, of a cam element having a pivoted bearing on the jaw and an edge that is disposed eccentrically to the bearing and is arranged to engage a rail.

In a device of the character described, the combination with anchoring means including a clamping-j aw having an overhanging rail-engaging bill, said bill being provided with a socket, of a tapering cam element having one end fitted in the socket and its opposite end provided with a cam-surface arranged to bear against the rail-web.

4. In a device of the character described, the combination with rail-embracing jaws, of freely-swinging cam elements mounted on the jaws and having rail-engaging surfaces disposed eccentrieally to the axes otmovement of said elements, the opposing ends of said surfaces thus moving toward each other upon the swinging movement of the elements in either direction.

5. In a device of the character described,

the combination with rail-embracing jaws:

having inwardly-extending bills provided with sockets, of freely-swinging cam elements having their outer ends pivotally mounted in the sockets and having eceentrically-disposed inner surfaces arranged to engage the opposite sides of a rail-web.

of rail-engaging means mounted movably thereon, and spaced devices separately connecting the jaws, one of said devices being adjustable to draw the jaws toward each other. v

8. In a device of the character described, the combination with rail-embracing jaws, of rail-engaging means movably mounted on the upper ends of the jaws, a device connecting the lower ends of the jaws, and a tiebolt connecting intermediate portion of the aws.

9. In a device of the character described, the combination with rail-embracing jaws, of rail-engaging means carried by the upper ends of the jaws, a device connecting intermediate portions of the jaws, and a connecting-plate having openings at its ends,

-said jaws having heads at their lower ends that pass through the openings and interlock with the connecting-plate.

10. In a device of the character described, the combination with an anchor-block arranged to be placed between two ties, of rail-embracing 'aws located on opposite sides of the block and having sockets 1n the inner sides of their upper end, cam elements pivotwlly mounted in the sockets and arranged to engage the opposite sides of a railweb, a tie-bolt connecting the jaws below the sockets, a connecting-plate extending beneath the anchor-block and having longitudinally-disposed slots, arid transverselydisposed heads carried by the lower ends of the jaws, said lower ends passing through the slots with the heads located transversely beneath the same. i

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
